IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 153,7 l2, dated August4, 1874 application filed May 25, 1874.

To all whom it may concern:

Be it known that I, JOHN HoLTvoIGT, of Dayton, in the county ofMontgomery and State of Ohio, have invented certain Improvements inWater-Wheels, of which the following is a specication:

The first part of my invention relates to an adjustable device, by whichthe gate may be raised and lowered as the circumstances may require. Thesecond part of my invention relates to an adjustable device connectedwith the gate adjustment for the purpose of lowering or raising thewheel at pleasure.

Figure l is a side elevation of -the waterwheel with the improvementsattached, and parts of which are shown only in section.

D represents a spider with four arms arranged at a right angle to eachother. To this spider is bolted the outer rim or case E. A circularorifice at the center of the spider supports the step C. The step isprovided with a feather to prevent its turning within its orifice. Nearthe top is a flange, and on either side of which are lugs, which restagainst the lever Q. In'other respects the step is constructed in theusual manner. The wheelshaft B has its lower bearing upon the step, andits upper bearing within the pedestal M, which is provided with padsadjusted to bear snugly against the shaft. In the drawing, Fig. l, thepedestal is shown elevated above its true position, which is on thecrown-plate P. to which it is securely bolted. The lever H passesthrough a slot in its side, and which orifice should be protected by adiaphragm connected to this lever. The crown-plate P is bolted onto thechute-case O. To one side ofthe crown-plate is a bearing for the gaterodL. To the lower end of this rod is attached a pinion, which gears intothe rack m, which is bolted onto the register-gate F. By this means thegate is opened and closed. On the top of the crown-plate is attached thepost n, to which the lever H is hinged. Thev opposite end of the leverrests on the nut a, which is carried by=the rod I. The inner end of thelever is circular, embracing the shaft, and to this circular partissuspended, by posts on either side, the sleeve Gr. The upper end of thissleeve has a journal fitted to the shaft. Bymeans of screwspassingthrough the flange of the sleeve, and their ends coming incontact with the crown-plate, theA descent ofthe sleeve to a given pointis readily adjusted. To the lower end of the sleeve is attached theplate S, which supports the registergate. The gate has a sleeve at itscenter, which embraces theintermediate sleeve V, which is bolted to theunder side of the crown-plate. This arrangement prevents any lateraldeflection of the gate. The wheel A is secured to the lower end of `theshaft, as shown in section at Fig. l, the buckets being shown inoutline. The outer line of the buckets is at angle of forty-fivedegrees, and the gate, which is intermediate between the wheel and thechute-case, all have parallel surfaces. The chute-case and theregister-gate have corresponding openings, and these openings direct thewater so as to act favorably on the wheel. Q is a lever having a centralcircular orifice embracing the step, which it supports. The left end ofthe lever is supported by a post fastened to an arm of the spider, andthe right end is sustained by the rod K,.to which it is jointed. Thisrod passes through a hole in the standard N, and to the top of which aplate is attached, which embraces the rod I. The nut c rests within asquare slot of this plate, thus preventing the nut turning when the rodis turned. The standard is bolted onto the chute-case, and gives supportat the top and bottom to the rod, which is so held that it cannot movevertically. Thus, by turning the rod, the nut is moved up or or down,carrying with it the lever and the impending parts and by this means thewheel4 is raised or lowered at pleasure, and the gate is carried by thesame movement.

The connection with the step may be broken, and the raising and loweringdevice used only to move the gate vertically', a small space only beingallowed between the chute-case and the wheel for the purpose.

In the operation of lowering the gate and wheel, the gate is onlylowered until the adjusting-screws in the flange of the sleeve come incontact with the crown-plate, then as the rod is turned the wheelcontinues to descend, leaving the gate supported by the crown-plate, andthe nut a moves down within the slot of the lever. The movement of eregister-gate is obstructed by the accumulation of sand between thesurfaces that come in Contact, and as by this device the surfaces areseparated the gute is always moved Without difficulty. Y*

What I claim as my invention is l. The combination and arrangement ofthe rod I, with its nut a, standard N, lever H, sleeve Gr, plate S,sleeve V, crown-plate I, and

register-gate F, substantially as described, and for the purposespeeied.

2. The rod I, with its nuts a :md c, in conibination with the operatingmechanisms for raising and lowering the wheel und gate, substantially asset forth.
